At a glance: eating in Noita is the S key (left stick down on a controller), and drinking a potion is right-click. But Noita has no hunger and no starvation — the Satiation meter only ever penalises you. You get Clumsy Movement above 100%, Choking Damage above 150%, a warning at 175%, and at 200% you explode for 100% of your HP.
So “how do I eat” and “how do I not die of hunger” are both the wrong question. The meter is not a survival bar; it is a status-effect delivery system with a bomb attached. Here is how it actually works, in numbers.
The five thresholds
| Satiation | What happens |
|---|---|
| 0–100% | Nothing |
| >100% | Clumsy Movement — reduced movement speed |
| >150% | Choking Damage — any further food you ingest deals damage |
| >175% | Bursting at the Seams — the game is telling you the next bite may kill you |
| 200% | You explode, harder than a Bomb, taking 100% of your HP |
There is a real use for that last row. The explosion opens passages, and Ambrosia lets you survive it — and, worse, lets you repeat it every time you eat. Extra Life survives it once. Neither is a strategy you should build a run on, because the satiation does not reset and every second above the limit keeps stacking penalties.
The speed penalty is the part players underestimate. 100% is not a safe plateau; it is the moment your movement starts degrading, which in a game where dodging is the primary defence is a real cost. Eating a big meal before a boss fight is a self-nerf.
How fast it drains
Satiation falls at roughly 1% per 6.25 seconds when you consume nothing. A full 100% takes about 625 seconds — 10 minutes 25 seconds.
Vomiting is instant and costs 10% per vomit, and it works even when your meter is empty. Two triggers:
- Food Poisoning — from eating Slime, Urine, or even your own Vomit.
- Whiskey — carrying more than 60 seconds of Drunkenness gives you Wasted, which brings Poisoned and vomiting with it.
Vomiting also wipes all ingested effects, with the exception of alcohol effects, whose durations are only drastically reduced. So it is not a free reset: if you ate something for its buff, vomiting takes the buff with it.
Eating for effects, not for food
This is the only genuinely good reason to press S. Status duration scales with how much you consume: every 10% of a potion, or every 100 pixels of material. Eating off the ground loses about 25% of the material, so a floor meal is a weaker version of the same meal from a flask.
The clearest example in the game is Hearty Porridge. A full potion gives 1.5 seconds of Regeneration and fills 80% of your Satiation. That is a real heal attached to a big satiation cost — useful when you are empty, bad when you are already at 90%.
Alcohol is the other deliberate use, and its stages are precise:
| Drunkenness duration | Stage |
|---|---|
| Any amount | Tipsy — blurred vision, slightly reduced accuracy |
| Over 15 seconds | Drunk — accuracy falls further |
| Over 45 seconds | Wasted — heavy blur, big accuracy loss, vomiting starts |
| Over 60 seconds | Poisoned for each second beyond 60 |
That Poisoned line is why “drink whiskey for the buff” turns into a vomit loop if you overdo it.
Flasks hold more than one potion at a time
Drinking consumes 10 percentage points of each material type in the flask. A flask that is 50/50 of two liquids therefore loses 20% of its contents per drink — 10% of each. That is convenient for carrying several potions at once, at the cost of fewer individual sips.
The trap is contamination. Drinking any amount of Oil harms you with an effect similar to Poison, and mixing a healing liquid with something caustic means every sip carries the caustic with it. If a flask has been sitting in a puddle, check it before drinking.
Two perks that rewrite the rules
Iron Stomach ignores every negative effect from eating — all the threshold debuffs, the damage from inedible materials, and the 200% explosion. With it, satiation stops mattering entirely. One quirk to know: if you later remove Iron Stomach at the Nullifying Altar, your satiation is set to 100%, and if that reset fails, the next thing you eat detonates you.
Eat Your Vegetables inverts the meter. Water no longer adds satiation; you have to eat Blood, Worm Blood, Meat, Hearty Porridge or Pea Soup instead. Below 25% satiation you take continuous Curse damage of roughly 0.7% of max HP per tick, and at 60% or above your damage goes up. It is the one build where eating is mandatory rather than optional. Take it before Vampirism, not after — the reverse order can stop Blood from giving you satiation at all.
There is also one piece of alchemy worth knowing while you are handling food: any variant of meat plus Alchemic Precursor creates Draught of Midas, which is the only route to that material.
What to actually do
- Never eat to survive. There is no starvation. If you are at 0% you are taking no damage from it, unless you have Eat Your Vegetables.
- Eat for the buff, then stop. Porridge for a heal, whiskey only if you want the accuracy trade, and never past 150%.
- Watch the meter before a boss. Above 100% you are slower, and the boss guide is full of fights decided by one dodge.
- Keep a vomit source if you plan to eat heavily: a flask of slime is cheaper than a run.
- Take Iron Stomach if you intend to use food as a mechanic at all — it removes the entire risk column.

The perk tier list ranks Iron Stomach and Eat Your Vegetables against the alternatives, and the common mistakes page covers the eating errors that end runs.
A note on version drift
The Feast Update reshaped how liquids and food are consumed, so this is a mechanic that has changed before. Every figure here — the S key binding, the 100/150/175/200 thresholds, the 1% per 6.25 seconds decay, the 10% vomit cost, the 10-points-per-material drink rule and Porridge’s 1.5s / 80% split — was read from the Official Noita Wiki in October 2026. Re-check the Satiation page after any update that touches food.
